selftests/bpf: Initialize tc in xdp_synproxy

Browse Source 
xdp_synproxy/xdp fails in CI with:

    Error: bpf_tc_hook_create: File exists

The XDP version of the test should not be calling bpf_tc_hook_create();
the reason it's happening anyway is that if we don't specify --tc on the
command line, tc variable remains uninitialized.

Fixes: 784d5dc0efc2 ("selftests/bpf: Add selftests for raw syncookie helpers in TC mode")
